10. Install the outboard spacers in the side from which they were removed.
11. NOTE: Remove all nicks, burrs, dirt, etc. from the differential case hubs, to allow the special tools to rotate freely.
Place the special tools of the differential case hubs and position the assembly into the differential housing.
12. NOTE: The rear axle uses a combination of differential bearing shims and selective outboard spacers to control differential case end play. The
old outboard spacers provide a good starting point when setting end play. However, if additional shimming is necessary, beyond what the hardened
differential bearing shims can provide, select and install different thickness outboard spacers.
Mount the special tools as shown. Locate the tip of the Clutch Housing Gauge on a flat surface of one of the bolts.
13. NOTE: Repeat this and the following step until the same readings appear on the indicator each time. This is the total differential bearing shim
thickness necessary, less preload. The final calculation occurs later during assembly.
Force the differential case as far as possible toward the indicator. With force applied, set the indicator at 0.
